Anybody have problems with this sh%t? We have a few patches of this stuff in two fields, we used the backpack sprayer last year & gave it a good dose of glypho, killed it, but this year it's back again & the patch is bigger. My dad is quite concerned about this weed, he wants to know if there are other or better sprays that will eliminate this stuff? TIA
